Title: Glitch elimination circuit
Inventor: TADA MASASHIGE
IPC: H03K5/01
Filed: 1990-02-06
Abstract: PURPOSE:To eliminate glitch by forming the circuit with a D flip-flop (D-FF), a capacitor and a resistor R only and preventing a short width pulse from being outputted by a time constant. CONSTITUTION:When a clock enters a point C, a signal at a terminal D is outputted to a terminal of a D-FF 8 by a leading edge of the point C and a terminal output Q goes to H, and since the point C is charged to a high level at a resistor R9 of the D-FF 8, the level at a point D goes to H. The level at the point D is discharged by a time constant comprising a capacitor C10 and the resistor R9 and the D-FF 8 is reset. When the pulse with a low level and a short interval is inputted to the input, the reset at the point D is released. Moreover, when a short interval pulse is inputted at a high level, since the timing when the output Q goes to L depends on the time constant comprising the capacitor C10 and the resistor R9, the output Q goes to an L level after a prescribed time.

Title: Exhaust gas temperature measuring apparatus
Inventor: IZUMITANI NAOHIDE
IPC: G01N27/41
Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To obtain an exhaust gas temperature measuring apparatus employing an air/fuel ratio sensor in order to eliminate a temperature sensor in view point of cost in which the exhaust gas temperature can be measured accurately without limiting the measurement conditions. SOLUTION: In an operating region where conduction to the heater in an air/fuel ratio sensor is not required, exhaust gas temperature is estimated by measuring the element impedance of the air/fuel ratio sensor. In an operating region where conduction to the heater is effected, element temperature drops when conduction to the heater is cut for a predetermined time Δt1 and the element impedance increases. Since increment ΔZ of the element impedance increases as the exhaust gas temperature decreases, exhaust gas temperature can be estimated by measuring ΔZ. Alternatively, exhaust gas temperature may be estimated based on the time Δt2 required for the element impedance increases to be reset to a value before conduction cut after conduction is resumed following to conduction cut.

IPC: C30B25/04
Filed: 1991-01-29
Abstract: PURPOSE:To grow a single crystal, whose abnormal nucleus generation is small, on a large-area substrate by a method wherein the substrate is heated at a low temperature and surface-treated in the gas atmosphere of a group V hydride generating active hydrogen at a low temperature as compared with hydrogen molecules or of an alkyl compound in which at least one hydrogen has been bonded to group V elements and, after that, a selective nucleus formation treatment is executed. CONSTITUTION:An amorphous film 1 whose nucleus formation density is higher than that of an amorphous substrate 2 is formed, e.g. by an EB, on the amorphous substrate 2 composed of SiO2, SiNx or the like. The amorphous film 1 is removed by, e.g. an RIBE by leaving a fine region. Then, the substrate is surface-treated in the gas atmosphere of a group V hydride or an alkyl compound in which at least one hydrogen has been bonded to group V elements. As an alkyl group (CnH2n+1-) for the alkyl compound, it is preferable that (n)=0, 1 or 2. At this time, a substrate temperature is set preferably at 550 deg.C or higher and 800 deg.C or lower, optimally at 750 deg.C or higher and 800 deg.C or lower. Thereby, a crystal can be grown without generating an abnormal nucleus.
